NEBS Inverters: Frequently Asked Questions

NEBS inverters are the result of equipment compliance standards that Bell Labs developed in the 1970’s. The standards were originally created to make it easy for manufacturers to produce equipment that could be implemented in the Central Office (CO) of a Regional Bell Operating Company (RBOC). Today, after being amended several times to stay abreast with technology, NEBS standards are widely used in the telecommunications industry and beyond.

If your organization needs inverters that meet a certain set of operating requirements, chances are that it could benefit from implementing NEBS inverters. The key is to determine what type of inverters are needed based on the environment where they will be used. If this is your first time shopping for commercial grade inverters, and you need more information about NEBS certification before you place an order, the answers below should be helpful.

How many types of NEBS inverters are there?

An inverter can be classified according to one of the following NEBS certifications: level 1, which meets the personnel and safety requirement of GR-63-CORE and GR-1089-CORE; level two, which meets the operating requirements of a specific type of environment, such as a data center; and level 3, which meets all the requirements of GR-63-CORE and GR-1089-CORE.

To which types of operating conditions do the levels of certification apply?

Level 1 certified devices are generally used for test purposes, as they have the safety requirements needed for testing, but may lack the ability to perform well under adverse conditions. Level 2 certified devices are used in a specific type of environment, outside of which they may be useless. Level 3 certified devices are used under adverse operating conditions.

What types of conditions are level 3 inverters designed to withstand?

Level 3 inverters are designed to withstand a broad range of adverse operating conditions, particularly: humidity, vibration, unusual temperatures, surge power faults, unusual altitudes, lighting strikes, airborne contaminants, and unusual acoustics. If you need an inverter that will withstand a certain condition, make sure it has been tested to with withstand the condition.

Is it a good idea to buy level 3 inverters as a safety precaution?

Buying level 3 inverters as a safety precaution is a good idea if the inverters will be used in an environment where various adverse conditions may or may not occur. Investing in Level 3 inverters is also beneficial because it allows you to migrate the devices to new environments without worrying whether they are capable of withstanding new operating conditions.
